InConsistency in volumes data from api

[PPC London]

Hello

I have seen many keywords which had reasonable volume in October 2015, but since then had no volume,eg, ax paris, philip glenister, a x paris, salisbury cathedral, news now, now, star now, faceboook. I checked on keyword planner as well. Please see attached screen shot of keyword planner.

Also I have another set of keywords for which api returned high volume up to October 2015, then api returned volume = 0 in Nov-Dec for all previous 12 months, now api is returning volumes for all previous 12 months again. Please have a look at attached screen-shot.

Any Idea whats going on? something is not right.

Many Thanks

Hello,

This issue seems better suited for our AdWords Community Forum. They should be able to figure out why the numbers are returning this way.
